Their arrest warrants allege they used a pistol to rob 18-year-old Morgan Mathis of money and/or a cellphone. Prosecutors say Hooper knew Mathis, and one of the two suspects held up Mathis at gunpoint while the other took the items from Mathis' pockets.

Saginaw County District Judge M. Randall Jurrens heard testimony regarding the incident during a Friday, July 11, preliminary hearing. He concluded the hearing by ruling prosecutors showed probable cause for McCaskey to stand trial in Circuit Court.

In addition to the robbery and conspiracy charges, which carry maximum penalties of life in prison, McCaskey and Hooper are charged with carrying a dangerous weapon with unlawful intent and three counts of possessing a firearm during the commission of a felony.

Hooper has remained at large since prosecutors charged him and McCaskey on June 18. He last lived at 2637 Narloch on Saginaw's North Side.

McCaskey remains jailed on a $70,000 bond.
